Napa Valley’s 2007 grape growing season was lengthy, with low yields, but extremely high in quality. Bud break occurred earlier than usual following a dry Winter and warm, dry Spring, but fruit set was inconsistent and left small berries in loose clusters. Cool weather in early Summer slowed ripening. In late August, the heat returned, but then unseasonably cool, foggy days chilled the second week of September, causing producers to leave grapes on the vine a little longer. A second heat wave at the end of September quickly finished up ripening the fruit. Although the growing season began early, the periods of cooler weather slowed maturation and caused harvest to conclude at a normal date, giving the grapes extra time on the vine. The small berries, typical of the 2007 season in Napa, developed intense varietal flavors and great concentration.
